United States Patent O 3,083,427 FILM CLIPBOARD William C. Grenen, 158%Coram Ave., Detroit 5, Mieli. Filed Dec. 18, 1961, Ser. No. 160,128 1Claim. (Ci. 24-84) This invention relates to a clip board for films, andmore particularly to a supporting clip board for the type of filmemployed in a Polaroid camera. Heretofore, in the use of Polaroidcameras, Land camera type, after the film has been exposed andthereafter removed from the camera, it is usually thereafter immediatelytreated by the user with a fixing solution which is normally rolled ontothe surface of the film, after which the film must be permitted to standfor several minutes until the fixing solution has become dry.

The difficulty heretofore has been that there has been no convenientdevice for mounting the film during the application of the fixingsolution or the rolling of the same thereon. Often this is done in thepalm of the hand, or on a piece `of furniture.

Another difficulty experienced is that after the film has been sotreated, no convenient location is provided for storing the film, orsupporting the film, or hanging the film until it has dried. The resultis that often times the film tips over on the wrong side and becomesscratched, dirtied or otherwise damaged `before the fixing solution hashad an opportunity of fully drying.

Accordingly the primary object of the present invention is to provide afilm clip board, which is constructed of a relatively thin and stiffmaterial, such as Masonite or plastic, and which has a clip mounted andsecured over one end thereof, which provides a means not only forsupporting the film upon the said board, but which also provides a meansextending therefrom for hanging the clip board during the dryingoperation.

It is another object of the present invention to provide a film clipboard for use in conjunction with films during a drying process thereof,or other processing thereof by which the film will be mounted upon aflat support and retained thereon, and with means -forsupportablyhanging the said film support in an upright vertical position.

It is the object of the present invention to provide a clip board forfilms which has Ia hanging hook, as an integral part of the clipassembly which is so constructed that the clip board may be suspendedfrom a line or other support surface or may be suspended from the belton the garment of the user, as one convenient means of protectivelysupporting the films until they have dried, but without interfering withfurther picture taking operations of the user.

These and other objects will be seen from the following specificationand claim in conjunction with the appended drawing, in which:

FIG. 1 is a front elevational View clip board.

FIG. 2 is a right side elevational view thereof.

Referring to the drawings, the present clip board is shown in fullscale. However, it is contemplated that the board may be of varioussizes, as desired, depending upon the film to be treated.

In the present preferred embodiment of the invention, there is providedan elongated fiat support plate which is constructed of Masonite, or aplastic material, but without the exclusion of other materials for thispurpose. The primary requirement, however, for the support plate 11 isthat it has a top flat surface 12 which is reasonably smooth.

A Z-shaped clip, preferably constructed of spring steel, or possibly aplastic material of sufficient resilience, is generally indicated at 13and includes a central body of the present film ICC portion whichoverlies the upper central portion of the plate 11 and is fixedlysecured thereto with a suitable fastener, as for example the rivet 14.

The present clip includes a central body portion, generally indicated at18, which extends over the central top edge of the plate 11, and belowthe fastener or rivet 14, which terminates in the downwardly extendingfilm holddown arm 15, which is bowed slightly outwardly from the frontsurface of plate 11, and at its lower end terminates in the slightlyoutturned film receiving lip 16.

The film is shown in phantom lines in FIGS. 1 and 2 illustrating how itwould be mounted upon the support surface 12 of the plate, the uppersurface of the film projected under the lip 16 and held down by the arm1S, forming a part of the resilient clip 13.

Ille body 13, `or central portion of the clip includes a downturnedmember 17 which cooperatively engages the rear surface of the plate 11and spaced below the top edge of the said plate is reverse `curved at19. The clip portion then extends upwardly to define the upright supportarm 20, which bears against the rear portion 17 of the said clip, andwhich extends upwardly beyond the upper edge of the plate and terminatesat its upper end in the reverse curved support hook 2-1.

This provides a means by which the clip board, or support plate 11, maybe suspended from a support such as a horizontally disposed wire, ahorizontally disposed rod, or any other horizontally `disposed elementor support means for suspending the said clip board.

It is contemplated that the clip construction shown in FIGS. l and 2represents a preferred embodiment of the invention, but that the clipmay be varied in form and in construction within the scope of the claimshereafter set forth.

Having described my invention, reference should now be had to thefollowing claim.

I claim:

A film clipboard comprising a thin, fiat, rigid board upon which a filmmay be placed, the board having a front face, a rear face and an upperedge and a clip secured to the board at said upper edge, said clip beingformed `of a single, fiat, ribbon-like strip of springy metal bent atits center into an inverted U-shape formed with a bight and two parallellegs spaced apart a distance approximately equal to the thickness of theboard, the U-shaped strip being arranged at the center of the upper edgeof the board and snugly receiving the board between the legs of the U,with the legs of the U being in full face to face contact with therespective faces of the board; the lower end of the leg of the Udisposed on the front face of the board being downwardly extended toform a bowed hold-down portion whose lower end is bent forwardly as alip; the rear leg of the U-shaped portion being integrally extended fromand reversely bent relative from its lower end to form along suspensionhook portion arranged in face to face contact with the full height ofsuch rear leg and extending above the base of the U-shaped part of thestrip a considerable distance and terminating in a downwardly andrearwardly bent hook; and a rivet extending through both legs of theU-shaped part of the strip, the board and also the suspension hookportion of the strip to join the clip to the lboard; the rivet forming aclamp for the hold-down portion so that the lower lip of the hold-downportion may be sprung forwardly from the Ifront face of the board toreceive and to tightly grip and spring press a thin film against thefront face of the board.
